"Application mea'nprn 4,'ll1e22. 'serian minieme. y

My invention relates kto new `and useful improvements ,in a tide motor, and has tor its primary object theconstruction' ofia 'device otl this character whereby the-powerl of tide waters may be translated into mechani- Another objeetof `this linvention is the 'provision y ofl a oat having `,a -dual valve structure for the inletand release ofwater.

`Agfurther object otftmyV inventionpisto provide a `unique meansfor actuating the.

dual valve structure.

, W ith these ends in view, this invention' consists in the details of constructionl and combination of elements v'hereinafter `jset yspecilically designated by the claims. I In4 order that thosef skilled in the" art to which my invention appertains mayunderstand how to'make and use the same, I will describe its constructionfin detail, referring -by numerals to the accompanying drawings forming Aa partof this application, in whims, f i y Fig. v1 isa Vfragmentary vertical sectional side elevation of the motor with the iioat at n its highest position. l e Figr2 is a similar' view at its` lowest po- Fig. 3 is ay plan view of the: floatwith a portion of the top wall'broken away to illusvalve. f

Fig. 4 is a fragmentary sectional .side elevation of the motor with the float in a position just ready to open for releasing the water` at the lowermost position.

In the bottom wall of the fioat is formed an opening 9 which may, if found desirable, Y be surrounded by two seats 1() and 11, the

former on the'inside and the latter on the i outside.k Theopeningis controlled byr a dual valve structure` comprising an vinner valve 12 coacting with the seat 10 and hinged as at 13 andan outer valve .14 coacting with i the valve seat 11 and hinged as at 15. The inner valve 12 is normally maintained in a closed position byk gravity `and has one'end of a rodA 16 loosely connected y therewith,- which rod passes through'the bottom wall wallsl vthe 'arcsjot circle'sij l through the' float wall itmay be packed in j any suitable'in'anner such packing being conventionally'shown'at 17. 1

lTo the outer valve 111 is looselyl connected and,r` if `foundA.desirable, may pass through tlie'tube19 having its ends fined inthev float The ro'dlS is'provided with a head 20 against which restsl oneend-ot aspring 21 while the other end engages thetop of the'viloat thus normally 'holding the fouter valvefin 'a closed position. l'lhetloat may heopen 'at the' top but il closed, as herein top wall. Y

lwith theirrespective"valvessaidyro'ds lmay F movev vertically while 4the valvesinove in Below `the ioat is'arranged a travel of the yrod* 18 for opening the dition colf.

rone end otherod `r18 whieh'passes through Vboth the top and bottom walls 'olf' the",float` lillustrated .an air vent k27`is yprovided inthe ystriker 22 vthep'ath or" travelot the rod 16 while above said float is another strikerQB inthe path ot' c ent valves as .will be hereinafter more' fully. *i i explained; v v v Y The movements of the float due tothe-rise and Jfall oftheI tide may be utilized in transmitting power :thus-derived to -suitablemaf chinery and asan illustration thereoiE Ihav'ev i shown the float asprovideduwith a'fraclr 24k meshing with a gear25 on a driven shatt26, i

it beingobvious to persons skilled in theart that the power may be transmitted yfrom the ishatt 26.iny any suitable manner. In carrying out my-invention as here em-k vno longer incontactl with the strilrerv22 andy as soon vas theV rod 18,` or its head 20, contactsA withv the striker .23 'said lrodrand4 the outer valvelto whichthe rod is connected will vloe arrested whereasthe-continued Iise of the tide will littthefloat until stopped by the inner 'or upper -valve 12, but as soonv4 as the afloat isr iilledor vat least `when the tide begins to turnfthe vweight of .theimler valve and stop' k5 so that the outery or` lower valve is 'opened permitting the rising tide j waters to "rush in through the opening 9 and raise ythe ict its 'component partswill causes/aid valve to close thereby retaining. the water. y IAs'the oat descendsgdueto 'the enclosed 1 no I body of Water, the head of the rod 18 Willbe disengaged from the striker 22, and the action of the spring 21 Will close the. outer valve 14. y

then the float, in its descent, reaches the position shown in Fig. 4, the rodl will engage the striker 22 thereby arresting said rod and the inner valve l2 to which it is connected but as the lioat `may continue to descend with the 'falling tide the opening` 9 will be again opened and the Weight ot the Water in the loat Will force the outer valve 14 away from its seat against the action of the spring 2l until most of the Water flows from the float or until such time as the tension of the spring is equal to the enclosed body ot Water when said valve Will be again closed by the spring` 21.

As soon as the tide again begins to rise it will litt the float and when the latter has reached a position such as shown in Fig. -l the inner valve will again close.

From the foregoing ldescription it will be noted that I have provided an exceedingly simpleand effective tide motor which may be located any desirable distance inland thereby greatly reducing the possibility of daniaoie due to ocean storms.

Ot course I do not Wish to be limited to the exact details of construction as herein shown as these may be varied Within the limits ot" the appended claims .Without departing` `from the spirit of my invention.

Having thus fully described my invention, What I claim as new and useful is z* l. A tide motor including` a float actuated by the rise and fall of the tide, said float having an opening` in its bottom Wall, and a 'dual valve structure controlling said opening said valve structure including` tWo separate valves operative independently of each other.

2. A tide motor including a float actuated by the rise and tall of the tide, said float having an opening' in its bottom Wall, an outer valve hinged on the outside oi' the float in the region of the opening, means for normally closing` said valve and an inside valve hinged Within the tloat in the region of the opening and normally closed' by gravity.

3. A tide motor includingva float actuated by the rise and tall of the tide, said float having an opening in its bottom Wall, means to arrest the descent of the float before the full tall of the tide, other means to arrest the float before the 'full rise of' the. tide, valves hinged on both sides of the bottom iva-ll et the float in the region of the opening therethrough to control said opening. one ot said valves being normally closed by gravity, means to normally close the other of sain valves, means to arrest one 01"' said valves before the float has reached lits lowest position, and means to arrest the other valve beterev the float has reached its highest position, said valves valso being operable by the rush of Water in or out of the float.
